SYNTHESIS AND CHARACTERIZATION OF NONAISOPROPOXODIZIRCONATOTIN(IV) COMPLEXES

A number of novel heteroleptic nonaisopropoxodizirconatotin(IV) complexes of the type [Sn{Zr-2(OPri)(9)}Cl-n(4-n)] (where n=1-3) have been synthesised by the reactions of SnCl4 with KZr2(OPri)(9), in benzene in requisite (1:1, 1:2, or 1:3) molar ratios. Replacement df chloride in these derivatives by an appropriate alkoxide affords volatile, heterobimetallic derivatives of the type [Sn{Zr-2(OPri)(9)}(n)(OR)(4-n)] (R=Pr-i, Bu(t), n=2 or 3). These novel heterometal alkoxides have been characterized by elemental analyses,molecular weight measurements, IR and multinuclear (H-1, C-13 and Sn-119) NMR spectral studies.
